Google cloud synchronous speech using local file

[sivaprasad1984]

Hi everyone,

I have a problem with google speech implementation in Qt (local audio file from my PC).
I got QtNetwork reply as network error(contentNotFoundError). google error string received as "Error transferring https://speech.googleapis.com/v1/spe...nize?key=mykey - server replied: Not Found".
My Qt code is below.
Any help is appreciated.

PrepareJsonAndPost()
{
    QString path = QCoreApplication::applicationDirPath() + "/" + "testAudio.wav";
    QFile file(path);
    bool fileOpenStatus = file.open(QIODevice::ReadOnly); 
    QByteArray byteArray = file.readAll();
    QString jsonData = byteArray.toBase64();
    convertAudioToSpeech(jsonData);
}
 
//Json request Post to google cloud
convertAudioToSpeech(QString jsonData)
{
    QNetworkRequest request(QUrl("https://speech.googleapis.com/v1/speech:recognize?key=myAPIKey"));
    request.setHeader(QNetworkRequest::ContentTypeHeader, "application/json");
    QLoggingCategory::setFilterRules("qt.network.ssl.w arning=false");
    QJsonObject jsonObject;
    QJsonObject configObject;
    configObject.insert("encoding", "LINEAR16");
    configObject.insert("sampleRateHertz", 16000);
    configObject.insert("languageCode", "en-US");
    jsonObject.insert("config",configObject);
    QJsonObject audioObject;
    audioObject.insert("content", jsonData);
    jsonObject.insert("audio",audioObject);
 
    QNetworkAccessManager *nam = new QNetworkAccessManager(this);
 
    QJsonDocument jsonDoc(jsonObject);
    QByteArray jsonBytes = jsonDoc.toJson();
    QNetworkReply *reply;
    //QEventLoop loop;
    reply= nam->post(request, jsonBytes);
 
     while (!reply->isFinished()) {
         qApp->processEvents();
 
    }
 
    if (reply->error() == QNetworkReply::NoError)
      {
          QByteArray response_data = reply->readAll();
          QJsonDocument document = QJsonDocument::fromJson(response_data);
          qDebug() << "OutPut : " << document.toJson(QJsonDocument::Compact);
      }
      else // something went wrong
      {
          qDebug() << "Json File Failed to Load : " << filename;
          qDebug() << "Error : " << reply->errorString();
          qDebug() << "Error Code : " << reply->error();
      }
